Submit to calculate the magnetic field inside a very long solenoid (only a relatively short segment of the solenoid is shown in the pictures), The segment of the solenoid shown in (Figure 1) has diameter D, and in turns per unit length with each carrying current I. It is Part B Complete previous part(s) usual to assume that the component of the current along the z axis is negligible. (This may be assured by winding two layers of closely spaced wires that spiral in opposite directions.) Part C Complete previous part(s) From symmetry considerations it is possible to show that far from the ends of the solenoid, the magnetic field is axial. Part D Complete previous part(s) Part E Find Bin, the z component of the magnetic field inside the solenoid where Ampere's law applies. Express your answer in terms of L, D, n, I, and physical constants such as #o- Submit Request Answer Part F Complete previous part(s) Part G The magnetic field inside a solenoid can be found exactly using Ampere's law only if the solenoid is infinitely long. Otherwise, the Biot-Savart law must be used to find an exact answer. In practice, the field can be determined with very little error by using Ampere's law, as long as certain conditions hold that make the field similar to that in an infinitely long solenoid. Which of the following conditions must hold to allow you to use Ampere's law to find a good approximation? a. Consider only locations where the distance from the ends is many times D. b. Consider any location inside the solenoid, as long as L is much larger than D for the solenoid. c. Consider only locations along the axis of the solenoid.
